回复：飞机或海路进出境，交不交I94海关都有记录。陆路没有记录。

下面是CBP原文。所以陆路出境一定交I94，才有离开美国记录。航空出境看来登机前刷护照就自动通知了海关/移民局了。
CBP only has complete records of the entry and exit of persons arriving and departing by air or sea. If you are a legal permanent resident and crossed at a land border, it is unlikely that we would have a record of your travels. Also CBP's records only go back to 1982, even for air trave
